An improved system and method for investigation of a wobbling surface of a sample with an electromagnetic beam, involving application of a beam directing dual reflection surface "prism" system, which, while effecting beam locus direction rotation of 90 degrees also preserves beam polarization state. The system allows causing an electromagnetic beam to access an otherwise difficult to access sample in, for instance, a vacuum deposition chamber, and enables achieving very closely spaced incident and spherical mirror reflected points of beam reflection from a sample surface in use.
